Application filed January 30, 1922, Serial No. 532,867. Renewed December 11, 1925.

This invention has reference to electric drier-s, more especially to compound line cover driers.

The broad object of the invention is to provide an electric drier which will be simple and practical in construction, and which will be economical and eiiicient in the performance of its intended. function.

A more specific object is to provide an electric drier including a. plurality of feed ing or transfer screws and devices capable of transporting covers, various food prodnets to be exhausted or cooked, eta, through the drier to deliver them from the drier at a location in proximity to the location where the articles to be dried enter the drier.

A. still further object is to provide in the improved electric drier a resistance plate or conveying platform capable of moving continuously through the drier and con structed to convey the articles to be dried.

A still further object is to produce an electric drier consisting of a plurality of feeding or transfer screws and a plurality of spiral feed members constructed to trans port covers to be dried through the drier, and to equip the drier with an electric heating apparatus, and also with resistance meme bers adapted to be in electrical connection with the heating apparatus and to serve as platforms for conveying the articles through the drier.

A still further object is to provide reliable feeding arrangements for positively and continuously conveying the resistance members or conveying platforms through the drier.

With the above objects in view, as well as others which will appear as the specification proceeds, the invention comprises the construction, arrangement, and combination of parts as now to be fully described and as hereinafter to be specifically claimed, it being understood that the disclosure herein is merely illustrative. and meant to in no way limit the spirit of the invention, slight changes in. details of construction and arrangement of parts being permissible so long as within the scope of the appended claims.

In the accompanying drawings forming a part of this specification;

Fig, 1 is a front elevational View of the drier, parts being broken away;

Fig. 2 is a side elevational view thereof looking from the left in Fig. 1, a part of the cover being removed;

Fig. 3 is a fragmentary elevational view looking from the right in Fig. 1;

Fig. 1 is a fragmentary top plan view on a reduced scale;

Fig. 5 is a sectional view on line 5--5 in Fig. 2, looking in the direction of the arrows;

Fig. 6 is a sectional view on line 6-6 in Fig. 2, looking in the direction of the ar rows; and

Figs. 7 and 8 are 2ll1 8l.(3 and a plan view, respectively, of the conveying platform or resistance plate of the drier.

Referring to the drawing in detail, the frame of the drier consists of a lower base 10, an upper base 11, and uprights 12 between the bases, there being a cover 13 sur rounding the uprights and preferably entirely or partially removable in order that the interior of the drier may be viewed at any time. The upper base may likewise be partially removable.

\Vithin the upper base are bearings for shafts 14-, 14, 14- and 14 upon the top ends of which are fixed worm gears 15 15', 15 and 15 gears 15 and 15 meshing with worm l6 and gears 15 and 15" with worm 16' upon main driving shaft 17 receiving its power from any source, as by means of the pulley 18. Each of the lower ends of shafts 14 14;, 1 F and 14 is provided with a flange 19 19, 19 and 19 secured as at 20 to feeding or transfer screws 21, 22, 23 and 24 each having threads 25.

The lower ends of the transfer screws are mounted in bearings 26 26, 26 and 26 carried by offset members 27 27 on the lower base 10.

Numeral 2S denotes a feed member mounted in the upper base 11 and having thereon a spiral 29 of non-conducting material, and numeral 30 denotes a feed member mounted in the cover adjacent the base 10. and having a similar non-conducting spiral 29. Shafts 31 31' of the feed members 28 and 30 are provided with sprockets 32, 32 carrying a chain 33, and integral with the lower sprocket 32 is a larger sprocket, rying a chain which is actua d t 1' the instrumentaiity of sprocket 36 an gear 37 meshing: with upon the main driving Obviously, when the pa all of the transf r screws a hers will be rotatc A conveying platform or resistance is adapted to have contnr through the drier when in operation .s platform or plate is centered from the iced member 30 to the transfer 23, thence to the feed meinher the transfer screws 22 l I to the feed member 30, whence it goes up the transfer screws 21 and ,..he conveying platform or resistance plate and the transfer screws and s i 1 feed hers may be of any cc for the purpose. As shown. th platform consists of a current r ber 39 to the opposite edges o secured carriers l0 of some material and each shaped l as at 41, to fit the transfer screws and e having a groove 42 to receive here 43, 43 of non-conductii opposite sides of the feed in 30. The upper and lower ou fer screws are suitably cc low the plates or platforms to enp' qe r screws. (Supposing a res' is on the transfer screws 21 in the drawing. Evidently. said rotate the platform is elevat of the screws, just abore plane of the guide meinhe this position, the spiral 29 of ti e ber 28 engages back 0 as the feed member 28 r their-e to upper guide members spiral 29 causes the pi" full length of said re inc the carriers direct v upon of the threads 25 of. thG Ufli 2 and 24c and releasin th guide members 4 Q and 24 rotate, the p 1 bottoms of the threads screws 22 and Here the feed member en platform. removes it screws 22 and and cause to the transfer screws 2' er portions of the three 21 and 23 pick the platr the spiral 29 has carried sa'id screws. and the next 3 the resistance plattorn'). up the screi..-; and 23 commences.)

The feeding or transler screws conz om the shafts A, i i, LL and 14: and t oti'set members 27. 2. are also insulated l the support bearing through the oer bushing; 48. The connection from transformer i l to the transfer screws is directly throue'h the offset members 27, 11". Evidentlr, there can be no leakage trough the feed members 28 and 30 for the is thatthe spirals 29 and 29 are of ii (in-conducting material).

Ilumeral represents a feed table whence i icles to be dried are placed upon the orms or plates when on the feed member :30. and represents a chute to receive the articles that are emitted from the drier and dropped into the receptacle 51. (The chute includes a guide arm 52 adjacent the d twirl e -1 and feed nieniher 30 adapted "unction in a manner to be de:- cribed.l,

ferring); more particularly to Fig. it to be remarked that the articles to he re placed upon the conveying plat- ".1 ta ce plates when at the posisaid figure. (flhatis. upon the members 43 adjacent the transfer 21 and 23, moving" toward said transscrews). Ii'nmedi'itely the spiral 29 of teed in ber 30. eng ping the rear 'ard edge of the conveying platform or resistance mores the same in ordinary manner piatform or plate properly engages the feeding or transfer screws 21 and 23. as shown at B in Fig. lVhen the transfer screws have elevated the conveying platform or resistance plate to the top of said screws, the position at which they are shown at C in Fig. 5, the spiral 29 of the upper feed member 28 transports the plata or plate along the upper guide memto the upper ends of the feeding or screws and 2%. as at D, the plator plate being made to engage said in about the manner already de- The platform or plate is now carcorn to the feed member 30, and thus to the transfer screws 21 and 23. .e guide arm 52 adjacent the feed memis'eonstructec and arranged to allow the platforms 01 plates to pass under it, but to strike the dried articles off the platform or plate, said articles passing down the chute 50.

It will be evident, that any number of platforms or plates may be passing through the machine at the same time.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is 1. An electric drier having a transfer screw adapted to transport articles to be heated, and electric means for heating said articles, the heating means being adapted to travel on, said transfer screw.

2. An electric drier having a plurality of transfer screws and a plurality of feed members, said screws and members being adapted to transport articles to be heated, and electric means for heating said articles, the means being capable of continuous travel upon all of said screws and feed members.
